Since it is a cold, how can it show the symptoms of the digestive tract? This question is quite interesting. Wu Shuo, director of the comprehensive department of the South Hospital of the Second Affiliated Hospital of Sun Yat-sen University, said that when catching a cold, 80% people will have symptoms such as fever, sore throat, stuffy nose, runny nose and sneezing, while 20% people have no obvious respiratory symptoms, but abdominal pain and diarrhea are more prominent. Wu explained that this is because they are also infected with the cold virus, but their goals are different. For example, coronavirus mainly invades the lungs, while rotavirus, adenovirus and norwalk virus mainly invade the gastrointestinal tract, causing abdominal pain and diarrhea. Therefore, causing gastrointestinal colds can cause symptoms similar to gastroenteritis.
"Although the weather is still hot recently, it is getting colder and colder in the morning and evening. Some people feel cold when they turn on the air conditioner, but they feel hot when they don't, so they are hot and cold. If their bodies are weak in adapting to the environment, like children and the elderly, they are particularly prone to gastrointestinal colds. " Wu reminded that the symptoms of gastrointestinal cold are easily confused with gastroenteritis. Patients can roughly judge whether they have a stomach cold or not from the shape and color of their stools.
1, Gastrointestinal cold: watery stool, no pus.
2, gastroenteritis: mushy stool, mainly caused by overeating, overeating and catching cold, unclean diet;
3, dysentery: there are red and white mucus in the stool, bloody stool.
Generally speaking, the differential diagnosis can be made by pricking the finger for blood test and stool examination. As long as the diarrhea is not particularly serious, the gastrointestinal cold can be cured within 1-3 days by taking a rest and forbidding greasy food (rice porridge is suitable for the gastrointestinal tract to get proper rest). If diarrhea is accompanied by symptoms of upper respiratory tract, such as sore throat, antiviral oral liquid and Radix Isatidis can be used. During this period, if diarrhea is serious, you should drink a small amount of light salt water several times to prevent electrolyte disorder caused by dehydration.
If you still have abdominal pain, diarrhea or even fever after 3 days of onset, you should be alert to bacterial infection. Experts believe that because the virus invades the upper respiratory mucosa for a long time, local bacteria will cause bacterial infection, and antibiotics need to be used properly at this time.
